SPECIFICATION formingpart of Letters Patent No. 628,964, dated. July 18, 1899.

Application filed April 25, 1899- $erial No. 714A04. (N0 model.)

To aZZ whom it may concern.-

Be it known that I, MAX STRAKOSCH, residing at Vienna, Austria-Hungary, have in-' vented a certain new and useful Improved Acetylene-Lamp, of which the following is a specification.

Acetylene-lamps of present construction sufier, among other disadvantages, from the inconvenience of having to clear the carbidreservoir of the carbid residues, this having hitherto been done in a very incomplete and tedious manner by means of a cloth.

The present invention has for its object to enable the carbid-reservoir to be cleared rapidly in a perfect and simple manner, this being done by means of apiston, by the motion of which by hand or by spring power the carbid residues are removed from the reservoir.

The accompanying drawings show the construction of an acetylene-lamp according to my said invention.

Figure 1 shows a vertical section of the lamp, and Fig. 2 a horizontal section.

The carbid-receptacle l is closed at its lower end by a hinged bottom 2, and it contains a perforated piston 3,whose rod passes through a tube 5 of the water-reservoir 6 to the outside, where it is provided with a pressing knob 7. In place of the piston-rod may be employed a helical spring 8, (indicated by dotted lines,) which presses at top against the bottom of the water-reservoir and at bottom against the piston.

The carbid is introduced in the form of a cartridge 9, which is preferably made of nonwaterproof material, such as blotting-paper, and is made of rectangular form, so that it can expand in the circular generating-chamber.

bottom of the receptacle by the piston 3 either by the pressure of the spring or by the fric- The cartridge is held down upon the tion of the piston-rod 4 in the stuffing-box at top. The cartridge is thus held securely in position,

When the spent carbid residue is to be re moved, the bottom 2 is opened and the piston 3 is forced downward, whereby the cartridge is-forced out and at the same time the chamber is cleared, so that only the under side of the piston requires to be wiped with a cloth. If the spring 8 is used, this will automatically force out the spent cartridge on opening the bottom.

Forkeeping theupper surface of the piston as clean as possible it is advisable to provide it with only a few perforations for allowing the water to gain access to the carbid. In place of the perforated piston may also be used a non-perforated piston that does not fit very tight in the chamber, in which case the water will find its way to the carbid through the interstices between the piston and the cylinder.

Having thus particularly described and ascertained the nature of this invention and the best means I know for carrying the same into practical effect, I claim- In combination, the lam p-bod y having a water-compartment in its upper portion and a gas-generating chamber beneath the same, a removable bottom to said gas generating chamber, and a carbidexpelling piston in said chamber having a piston-rod extending up through the water-compartment to the top of the lamp, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

MAX STRAKOSCI-I.
